For all Natural Selection fans, this is a must download! This new version has some nice new features in it, including a new teammate order icons, a fantastic new map called "ns_shiva", minimaps with location names, updated skulk wall-walking, a boost to grenades, map updates and much more.
Natural Selection is a multiplayer Half-Life mod in which the Trans System Authority Frontiersman (Marines) battle the vicious Kharaa (Aliens). NS first came out in only one mode, what is now known as Classic. This is the Real-Time Strategy/First Person Shooter (RTS/FPS) version and is used for competitive play. Combat was added in version 3.0 and is a faster, more action oriented mode. It has elements of an RPG in that players gain levels that they can then spend on equipment, weaponry, classes, and abilities. The game is geared towards fast action with no building required
Server notes: To patch your existing NS 3.0 server, unzip this patch into your hlds directory. It will create an ns directory, and overwrite server.cfg and mapcycle.txt. If you backup your mapcycle.txt and restore it, don't forget to add ns_shiva
